Pre-wave pulse (PWP). The apparently whole-embryo calcium pulse appears to initiate (the PWP region on the wave graphs) over a widespread area of blastoderm, possibly earliest at the animal pole, and...

Four cell stage zebrafish embryo, stained with 100 micromolar Bodipy 505/515. In the upper portion of the image, the yolk cell contains large spherical yolk platelets. The blastomeres undergoing merob...

Zebrafish Embryo, from tailbud to 16-hour stage, stained with 100 micromolar Bodipy-Ceramide. Bodipy-Ceramide permeates the enveloping layer epithelium of the embryo, accumulating in the interstitial ...

Camera lucida sketches of the zebrafish embryo at selected stages. This image is in the Blastula period at the 2.75 hour 512 cell stage. The animal pole is to the top for the early stages, and anteri...

Camera lucida sketches of the zebrafish embryo at selected stages. This image is in the Blastula period at the 3.3 hour high cell stage. The animal pole is to the top for the early stages, and anteri...

Camera lucida sketches of the zebrafish embryo at selected stages. This image is in the Segmentation period at the 14 hour 10 somite stage. The animal pole is to the top for the early stages, and ant...

Camera lucida sketches of the zebrafish embryo at selected stages. This image is from the Pharyngula period at the 31 hour Prim-16 stage. The animal pole is to the top for the early stages, and anteri...

Camera lucida sketches of the zebrafish embryo at selected stages. This image is from the hatching period at the 60 hour pec-fin stage. The animal pole is to the top for the early stages, and anterio...

Camera lucida sketches of the zebrafish embryo at selected stages. This image is from the hatching period at the 72 hour protruding mouth stage. The animal pole is to the top for the early stages, an...

This study of the zebrafish eye is a series of four images taken at increasing magnifications. The first image is the SEM block face of the zebrafish eye. This is followed by a second image that is ...
